REGISTER AND AUTOMATIC STOP.

SPECIFICATION forming part of Letters Patent No. 410,242, datedSeptember 3, 1889.

Application filed February 11, 1889. $erial No. 299,550. (No model.)-

T aZZ whom it may concern.-

Be it known that I, CHARLES J. HARTLEY, of the city of Decatur, countyof Macon, and State of Illinois, have invented a certain new and usefulRegister and Automatic Stop, of

which the following is a specification.

My invention is particularly designed to register the number ofoperations of grainweighers and automatically stop the same at thecompletion of any predetermined number of discharges; but otheranalogous uses are readily apparent.

In the drawings accompanying and forming a part of this specification,Figure 1 is a face I 5 view of my device. Fig. 2 is a rear view with therear plate and stop mechanism detached. Fig. 3 is a rear elevation ofthe complete device, and Fig. 4 is aside elevation of the same.

The face of the casing to has the graduated dials Z1 and c, the oneindicating multiples of the other. Hands d and d are pivoted at thecenters of dials b and 0, respectively. They are mounted, the one on apin projecting through the casing from the center of the gear-wheel eand the other on a pin projecting from ratchet-wheel f. Pinion g mesheswith wheel 6. -A long tooth g on wheel f advances the pinion one toothat each rotation of the wheel, and wheel e is correspondingly goadvanced. Arm k is actuated by the device the movements of which it isdesired to register, connection being made therewith from theperforation n. Pawl Z is pivoted on the arm and held in contact withwheel f by spring 5 on. By the use of the pawl the oscillatorymotion ofthe arm is transferred to the wheel as intermittent rotary motion.Clicks 1' and h prevent back motion in wheels 6 and f. The wheels havebosses e and f and threaded pins 6 and f. Circular disks 8 and 'u. aremounted loosely on pins 6 and f", respectively, and are held in closecontact with the bosses, when desired, by set nuts t and c.

The disks 3 and a are graduated and numbered the same as theircorresponding dials h and 0, except that the direction of progression isopposite and they have the peripheral notches 8 and a. Bar 20 haslongitudinal motion in brackets q and z, and it tends to move downwardthrough the influence of gravity and the pressure of spring ,2". Arm

w is secured to the bar in a manner permitting adjustment and has acatch adapted to notch 8. Arm w is also adjustable on the bar and has acatch adapted to notch a. Lever 0 pivots on lug p and has thecrank-extension 0', which is slotted at 0 to receive pin x of bar to.The arms 10 and 10 rest ordinarily on the disks and hold the head 10ofbarwsome distanceabovebracketq. Lock- 6o arm 0", when swung under head20', as shown in Fig. 4, renders the stop mechanism inoperative. At y isshown an end of a trip-lever, which rests on the end of lever 0 andconnects with the weigher or other mechanism in such manner as to stopthe same when unsustained. \Vheel f and pawl Z are in one plane. Toothg, pinion and wheel (2 are in a slightly-different plane, so that thepawl will not be effected by the long tooth. The small diameter of thepinion enables the long tooth to mesh readily with the teeth of thepinion, and by the use of the pinion the wheels are rotated in the samedirection. As arm 7.; is actuated wheel f is advanced tooth by tooth andhand d pointby point until a complete rotation of the wheel f iselfected, when tooth g willhavc advanced the wheel e one tooth and thehand (l one point. The unit of rotation of hand cl with the graduation,as shown, is forty, and so So the divisions of dial 7) representmultiples of that number. It is obvious,- however, that by changing thewheels and graduations the unit of rotation may be varied.

In Fig. 3 the device is shown as set to stop on the completion of fourhundred and twenty movements, and the catch of arm w is over the number400 on disk .9, while the catch of arm 10 is over thenumber BOondisk u.The disks are numbered backward and move backward, so that when fourhundred movements have been made notch s, which is at zero, will beunder the catch of arm to, and when twenty additional movements havebeen made notch u will be under the catch of arm 10'. This coincidencepermits the bar to descend, swinging the end of lever 0 clear of thetriplever y, and so effecting a stop.

To set the device so as to stop upon the completion of acertain numberof operations, which number may be represented on disk 3, arm to israised sufliciently high to be inop erative, and, the disk 5 is set withthe desired number under the catch of arm w;

The stop is adjusted'by loosening the setnuts t and o, turning the disks8 and u to the numbers that the register is to stop at, and thentightening the nuts tand o, so as to hold the disks 5 and u firmly ontheir sleeves.

I elaim 1. A stop for registers comprising the gradu ated and numbereddials, the disks rotatingly adjustable on the dials, numbered tocorrespond with the dials, but in the reverse direction, and havingperipheral notches at the zero-points, and a longitudinally-movable barhaving catches adapted to the notches and resting ordinarily on theperipheries of the disks, as set forth.

2. A stop for registers comprising the gradu 1 a'ted and numbered dials,the disks rotatingly adjustable on the dials, numbered to corretodrawthe bar downward, and lever 0 0, connected with the bar, as setforth.

In testimony whereof I sign my name in the presence of two subscribingWitnesses.

CHARLES J. HARTLEY.
